Ah, how cool, I didn't know that one, although I'm collecting them (I have mostly Polish stamps)!
Yeah, me too, I like it when the visual style of these posters is used for totally different themes and illustrations. I'm so much looking forward to creating my first own poster!
Maybe I can show it to you when it's finished and not too ugly
You're very welcome, generally I like your illustrations very much, not just this one!
